Abstract

Bone marrow Mesenchymal stem cells capable of differentiating into neuronal cells on engineered nanofibrous scaffolds have great potential for bionanomaterial-cell transplantation therapy of neurodegenerative diseases and injuries of the nervous system. MSCs have been the highlight of many tissue engineering studies mainly because of their multipotential properties. We investigated the potential of human bone marrow derived Mesenchymal stem cells (MSCs) for neuronal differentiation in vitro on poly(L-lactic acid)-co-poly-(3-caprolactone)/Collagen (PLCL/Coll) nanofibrous scaffolds. PLCL and PLCL/Coll nanofibrous scaffolds were fabricated by electrospinning process and their chemical and mechanical characterizations were carried out using SEM, contact angle, FTIR, and tensile instrument. The differentiation of MSCs was carried out using neuronal inducing factors including beta-mercaptoethanol, epidermal growth factor, nerve growth factor and brain derived growth factor in DMEM/F12 media. The proliferations of MSCs evaluated by MTS assay showed that the cells grown on PLCL/Coll nanofibrous scaffolds were comparatively higher (80%) than those on PLCL. Scanning electron microscopy results showed that MSCs differentiated on PLCL/Coll nanofibrous scaffolds showed neuronal morphology, with multipolar elongations and expressed neurofilament and nestin protein by immuno-fluorescent microscopy. Our studies on the differentiation of MSCs to neuronal cells on nanofibrous scaffolds suggest their potential application towards nerve regeneration.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Introducing collagen, gelatin and fibroin into PLCL significantly improves cell adhesion ability of PLCL nerve conduit and promotes migration adhesion and growth of nerve cells.

    “By introducing collagen, gelatin and fibroin into PLCL, the cell adhesion ability of PLCL nerve conduit can be significantly improved, and the migration adhesion and growth of nerve cells can be promoted [183, 184].”
  • Preparation of PLCL into oriented or patterned spinning is beneficial to differentiation of neural stem cells and establishment of signal pathways between nerve cells.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
